To all whom it may concern: I clog the seats and make it diflicult to place Be it known that we, EDWARD XV. TURNER i the blanks in the carrier in operative posiand HERMAN S. BEAMS, citizens of the tion, pneumatic gathering means have been United States of America, residing at Richprovided. This device consists of a hood mond, county of Henrico, State of Virguua, or housing for the shaping cutter, open tohave invented certain new and useful Im' Ward the carrier, and suitable means'lfor provementsin Machines for Making Clothesexhausting the air from the hood. It was Pins, of which the' following is a specificafound that this device, while quite effective tion. for the purpose intended, had a tendency to This invention relates to an automatic displace the blankson the carrier adjacent machine for making clothes pins and has as the one being out. It will be noted that the an object the improvement of such machlne carrier is in the form of a hollow cylinder whereby the certainty of its operation, its and that the seats are provided with slots output, the quality of its work, and, therewhichextend to the inside of the cylinder. fore, its efliciency are greatly increased. To further provide for the removal of dust,

The machine to which our invention has to counteract the tendency of the pneumatic gatherer .just described to remove the blanks from theseats and to assist in feeding blanks to the seats, a second pneumatic gatherer is placed'inside the carrier with its mouth beneath the seats which are covered by the first gatherer. The mouth of the second gatherer also extends beneath the seat which is in feeding position; 6., receiving the blanks being fed, In this'way, the air-pressure on the blanks is neutralized and the tendency on the 'part'of the upper. gatherer to displace them-wholly counteracted to the extent that the pneumatic gathering device beneath the seats operates as a means for holdingthe blanks in their'sea'ts and assists in feeding the blanks to the carrier.

consists of a shaping cutter, a slotting cutter, and an intermittently moving carrier having seats for blanks. The pin blanks are placed each in a seat on the carrier and each remains in its seat until the operation of makingthe pins is completed. The carrier presents the blanks to'the shaping cutter. They are engaged by a live and a dead center, rotated in contact with the shaping cutter from which they receive the desired form, and released by the centers and carried on to the slotting cutter where they are clamped and slotted. The clamp is released. as soon as slotting is completed and the pin moves forward, still in its seat, until it is over a receptacle into which it is dropped. The invention relates to a number of mechanisms which will be referred to in the order in which they are brought into action in the operation of the machine.

In accordance with this invention, a re ciprocating-member, called a plunger, is provided adjacent the end of the belt. The blanks are supplied to the belt and rest thereon in a line extending out onto the plunger which supports the forward blanks of the line. A presser is also provided which reciprocates vertically. At each reciprocation of the plunger, a blank is released, and as the presser descends the blank ispushed into the path of the plunger. As the plunger advances, it engages the blank and moves it to the carrier, thus giving a positive feed to the blanks by which they can be handled as fast as desired without danger of the misplacing of a single blank.

For the urpose of preventing the accumulation o dust and shavings which would a high speed and the draft thus caused,'together with the flying chips, tends to displace the blanks in the seats adjacent the one occupied by the blank being shaped. The pneumatic device just referredv to serves to partly overcome this tendency. As a further means to this end, the invention pro vides a clamping device which operates during the shaping of each blank to hold in position the blanks adjacent the one being shaped. Thus, at each stop of the carrier, one blank is engaged for shaping and the blanks adjacent thereto are engaged by a clamping device. lVhen shaping is conipleted and the carrier is about to start, the blanks adjacent the one just shaped are released and they move on independently of the clamps.

During shapinggthe blanks are held and rotated between a live center and a shiftable center. The latter is actuated to slide in the direction ofits axis toward the live sea- In shaping the pins, the cutter rotates at 3 when shaping is complete. pose of ejecting finished pins from the seats,

ter and clamp the blanks between the two. Thelive center, as will be understood from the term applied to it, is constantly rotated and as the blank which is loose in the seat approaches the rotating center, propelled by the shiftable center, there is danger of some projecting chip on the blank being engaged by the rotating center, whereby the blank'will be displaced before it is clamped, and so caused to be clamped off center. To prevent such displacement of the blank and hold it in alinement as it approaches the live center, a pin is mounted in the live center with its axis coincident with that of the center to slide in the direction of the axes of bbth. This pin normally projects from ,the center and the recess in which it is pletely withdrawn within the center. A spring in the recess maintains the pin in the position referred to as normal. The pin is pointed at its. outer extremity and this point comes first in contact with the end of the pin blank as the latter approaches the live center, moved along the seat by the shiftable center. i

. The spring yields as the blanks advance and the latter is heldin position by the pin, properly centered, and in that position engaged by the live center. This pin also serves an important function as a means for disengaging the blanks from the live center For the pura cam surface is provided which overlies the surface of thecarrier. and is inclined in a cylindrical plane. This cam surface is in the path of the ends of the pins, stationary and back of the position of the last operation. As the pins come into contact with this surface, they are moved in the direction of their length, each pin sliding along its seat until it projects therefrom a suiiicient distance to be engaged by another cam surface in the path of the displaced pins. This surfaceis inclined outward in a plane transverse to the axis, of the cylinder. By this means, the pins are lifted from their seats and fall, to be collected in a suitable receptacle;

Sufficient of a machine for making clothes pins to show the application of our invention is illustrated in the accompanying drawings of which,

Figure 1 is a plan of the machine; Fig. 2 is an elevation of the machine from the feed side, with the feed mechanism removed; Fig. 3 is a detail of the feed mechanism and carrier; Fig.4 shows a part of the rim of the carrier in perspective; Fig. 5 is a broken section through the rim of the car,- rier; Fig. 6 shows in plan one of the slotted seats in the carrier; Fig. 7 is a View in perspective of a part of the feed mechanism; Fig. 8 is'a detail of a connection between mounted is sufficient to allow it to'be comcarrier 2, a shaping cutter 4-, with means whereby it is oscillated toward and from the carrier and rotated, and a slotting cutter 8, also mounted to oscillate toward and from the carrier and to rotate. The carrier 2 is rigidly mounted on the shaft 5 journaled in the frame of the machine and extending transversely thereof. This shaft is driven intermittently by means of a toothed wheel 6 mounted thereon and secured to the shaft. This wheel is engaged by a segmental. worm 7 mounted on the cam shaft 8. The toothed wheel 9 is secured to the shaft 8 and meshes with a smaller toothed wheel 10 mounted on an idler shaft 11 journaled on the frame of the machine. the other extremity of this shaft. A. belt 1.4 runs over this pulley and a pulley 15 on the main shaft 16 which is driven by a suitable belt frcm a counter shaft not shown, said belt running over the drive pulley 1? on the main shaft. The carrier, or carrier drum, as it will be hereinafter termed, shown in detail in Figs. 3, a and 5, consists A pulley 12 is secured to of a hollow cylinder having at one end the web orv spokes 20 transverse to the axis. The hub 21 which is lntegral with the web is mounted on and rigldly secured to the shaft 5, as previously described. The outer cylin-,

23 extending from the edge of the cylinder Each groove or seat 22 is conwhich is remote from the web 20 toward the web. These slots are preferably centrally placed in each groove and in a radial axial plane of the cylinder. They are of a width in excess of the width of the slots to be made in the pins and are enlarged adj acent their months 24- to admit the cutter which is formed to make a correspondingly shaped.

slot in the pins.

The shaping cutter 4 to which the blanks are presented first after being deposited upon the carrier consists of a series of blades 25 shaped to give the desired form to the blank and mounted upon a head 26. This head is secured to a shaft 27 journaled in the swinging frame 28. A. quarter turn belt i 30 (see Fig. 1) passes over pulley 29 on this shaft and the pulley 31 on the main shaft 16. The -swinging frame 28 is journaled at its lower extremity in suitable bearings 32 on the frame of the machine. The lever 33 is pivoted intermediately at 34. and carries at one extremity a cam follower 35 which cooperates with the cam 36 on the cam shaft 8, and at its other extremity is pivotally secured to a connecting rod 37 which is pivotally attached at its other extremity to the frame 28. A spring '70 maintains the follower in contact with the cam. The spring 70 encircles the rod 71 which is pivotally attached to the lever 33 and passes through the guide 68 attached to the frame of the machine. This spring is in compression, and bears against the guide 68 and against the shoulder 18 on the rod 71. By this means motion. of the cam 36 is communicated to the cutter 4 moving it toward and from the carrier 2; at the same time, the cutter is continuously rotated, the power being transmitted from the main shaft as described.

The slotting cutter 3 is journaled on an oscillating frame 39 (see Fig. 1). A pulley 40 is mounted on the shaft and the belt 41 passes over this pulley and a pulley 42 on the main shaft 16. Oscillatory motion is communicated to the frame 39 by means of the connecting rod 43-to which is connected. the strap 44 of the eccentric 45 rigidly mounted on the cam shaft 8.

The operation of the elements described is quite apparent. Each cutter is rotated con tinuously. One oscillation of each cutter, whereby it engages the work, takes place during each complete step of the carrier. The pins on the carrier, as they advance, are first shaped and then slotted, each operation being performed on a different blank at each step of the carrier and each oscillation of the cutters.

An endless conveyer 48 is mounted on gears 49 and 50 journaledin suitable brackets, (see Fig. 3). This conveyer is driven by the large pulley 51 mounted on the shaft 52 of the sprockets 49. A belt 53 passes over the pulley 51 and a small'pulley'54 mounted on a horizontal shaft 55 connected by a suitable train of bevel gears to the cam shaft 8, (see Figs. 1 and 2). A hopper 56 having a vertical outlet at 57 opening on to the uppersurface of the conveyer belt is mounted on suitable brackets on the frame of the machine. It will be noted that the conveyer 48 terminates an appreciable dis-- tance from'the carrier. As shown, this distance is equal to about six times thediameter of the pin blanks in use, though it may be varied according to the judgment of the designer. To support the pins immediately beyond the conveyer chains, ways 58 are provided, the upper surfaces of the ways being continuous with the upper surface of the conveyer belt. These ways are shown clearly in detailin Fig. 7, which is a perspective of the end of the conveyer chains, the ways and the plunger 59, to be described.

In the embodiment of our machine shown, the conveyer consists of two chains or belts which run in grooves in a supporting table 60. This table is normally substantially horizontal, though its angle is adjustable by means which it is thought unnecessary to describe. The chains are spaced apart a distance depending on the length of the blanks to be used. The ways 58 consist of two parallel flat bars which, as previously described, have their upper surfaces continuous with the upper surface of the belt. These bars are secured to the side frames 61 and are, as stated, alined with the chains of which the conveyer belt is composed, though they may be otherwise placed. Between the ways 58, mounted to slide relatively thereto, is a plunger 59, the flat upper surface of which is parallel to the top surface of the ways 58 and the belt 48. This plunger extends beyond the ends of the ways, is grooved transversely along its front surface at 62 to engage the pin blanks and is connected by means of the L-shaped arms 63 to the end of the lever 64. The upright arm of the L is secured at its upper extremity to the plunger and the horizontal arm is swivele'd to the lever 64. The plunger slides upon the table 65 which is slotted for the passage of the arm. The lever 64 is pivotally mounted 66 (see Fig. 1) near its central point on the frame of the machine, and is oscillated about its center by means of the cam 36.. As previously described, this cam gives to thelever 33 an oscillatory motion about the center 34. This motion is communicated to the lever 64 by means of the flat connecting rod 67 pivotally connect-- ed at one extremity to the lever 33. The connecting rod 67 is connected at 69 by means of a pin and slot to the extremity of the lever 64. A spring 72 is interposed between the extremity of thelever 64 and a shoulder 7 30h the rod 67. This is a spiral compression spring, as shown, and serves to maintain the pin 74 carried by the lever 64 normally at the outer end of the slot 75 of the connecting rod 67 (see Fig. 8). The spring 72 and the slot and pin connectionv 75 provide for yielding between the cam 36 and the plunger. I

Journaled in suitable brackets on the frame of the machine above the conveyer and extending transversely thereto is a rock shaft 76 also actuated by lever 64. A depending arm 77 secured to one extremity of the rock shaft is connected by means of the link 78 to arm 63, (see Figs. 3 and 7 One extremity of the presser arm 79 is secured to the rock shaft 7 6 near its central point. The forward extremity of the presser arm is provided. with a presser foot 80 which is over the plunger in its forward position.

ger 59, and that the members 59 and 80 are so timed that as the plunger is withdrawn, the presser foot moves downward toward its path. Overlying the conveyor belt at each side and spaced from the table 60 a distance sufficient to permit the passage of the blanks, are two retaining guides 81, each in the form of aflat bar. At their forward extremities, these bars are bent down at right angles forming steps 82 which extend nearly down to the plane of the top of the plunger.

In the operation of the feed, the hopper 56 is supplied with blanks which move down into the outlet 57 propelled by gravity. It will be noted that the side of the outlet toward the carrier terminates above the table 60 a sufficient. distance to permit passage of a blank of the size shown. The conveyor belt is driven in the direction of the arrows so that during the operation of the feed, each blank as it reaches the surface of the table is moved forward between the guides 81 and the table and conveyer, forming a continuous line extending to the stops 82. The friction of the numerous blanks on the belt is sufficient to propel those in advance of it when they reach the ways 58 and the plunger, so that the line is maintained continuous up to the stops, those at the forward extremity being supported by the plunger. T Vhen the plunger is withdrawn described, the support is removed from the forward blank. The presser 80, so timed as to move downward at this time, as previously described, pushes the blank into the path of the plunger, at which period it rests on the table 65. The presser is immediately withdrawn and the plunger advances, engaging the blank and depositing it in one of the seats 22 of the carrier. The latter is so timed as to bring a seat into line with the plunger 59 at each step. If for any reason the blank is not properly placed, yielding occurs between the lever .64: and its cam, as previously described.

Adjacent the path of the carrier seats 22 at the point where the path of the shaping cutter f in its oscillation approaches nearest to the path of the seats are the live center 83 and the shifting center 8% (see Fig. 9). These are so placed that at each step of the carrier the axis of a seat 22 is made to coincide with the axis of the centers. The live center is driven in continuous rotation by means of the bevel gear 85 which meshes with a bevel gear 86 on the cam shaft 8. The shaft 87 of the bevel gear 85 is mounted in suitable bearings and connected by.

means of a universal joint 88 with the stock of the machine to slide in the direction of the common axis of the two centers. The motion of a substantially vertical lever 92 pivoted intermediately of its length at 93 to the frame of the machine (see Fig. 2), is communicated to this center by means of a connecting rod 9 1- at the upper extremity of the lever. A substantially horizontal rod 95 is pivotally connected to the lowerend. of the lever 92 and extendsthrough the machine to a point beneath the cam shaft 8 where it is pivotally connected to a follower rod 96. The latter is mounted on a stud 97 below, on the frame of the machine to swing in a vertical plane and carries at its upper extremity a roller 98 which engages a cam 99 mounted on the cam shaft 8 (see Fig. 1).

The centers are normally spaced apart a distance considerably greater than the length of a blank. The operative extremity l of the live center is a slight distance to one side of the path of the ends of the blanks and the corresponding extremity of the dead center is a considerable distance to the other side of the other end of the blanks. cam 99 is so timed that at each step of the carrier, as one of the seats 22 is brought into position with its axis coincident with that of the centers, the s'hiftable center 84:

is advanced and moves the blank longitu= dinally toward the live center until it is engaged thereby and rotated between the centers.

The outer extremity of the live center 83 is provided with teeth 100 to engage the end of the blank. It frequently happens that the blank is roughened and fibers of wood project therefrom. These fibers sometimes come in contact with the teeth of the live center as the blank approaches and the rapidly rotating center throws the blank out of line so that it is either entirely displaced from the seat or clamped off center. To prevent this occurrence, the live center is provided with a sliding centering pin 101. The center is bored axially its full length and the pin is mounted in the bore. The pin exceeds the center in length by a considerable extent and a collar 10?. is placed on the pin outside the center and adjacent 1 its back end to limit the forward movement of the pin. The center is placed in the usual conical seat in the extremity of The collar 102. One function of this pin is to disengage blanks from thecenter when the cutting operation 15 finished; also, when a blank pushed by the live center engages the point of the centeringpin 101, the pin is gradually moved backward against the tension of the spring 105 as the end ofthe blank approaches the live center. In this way,,the blank is subjected to a preliminary clamping action by which it is centered as soon as engaged and held as it approaches the live center and prevented from being displaced by the rapidly rotating teeth 100 of that centerwhen it first comes in contact with them. In Fig. 9, a blank is shown in position between the centers; the ends of the blank being broken away to show r the ends of the centers.

During the shaping of the blanks, partly because of the draft created by the rapidly rotating cutter and partly due to the action of the flying chips thrown ofi' by this cutter, the blanks adjacent that engaged by the live center are frequently displaced from their seats on the carrier. To prevent this action, the shiftable center is provided with clamping rods 107, one on'each side of the center and spaced therefrom so that they are alined with the seats adjacent the seat which is in line with the centers. The rods 107 are mounted to slide in suitable bearings 108 and in a crossbar 109 rigidly mounted on the stock 110 of the back center. Each rod 107 is provided with a collar 111 and a spiral compression spring 112 encircles each rod between the collar 111 and the cross bar 108 (see Fig. 9). Lock nuts 113 on each rod limit the motion of each rod in response to thetension of the spring and thereby give it its normal position. A plate spring 114 is secured to the feed frame and extends along the extremities of the seats on the side of the carrier toward the live center. This spring forms a back rest or abutment for the blanks and is apertured at 115 to allow the live center to pass through it. A rigid rest or abutment 116 mounted on a suitable bracket secured to the frame of the machine is placed opposite the extremities of. the

seats. beyond the live center.

As the back center moves forward before each shaping operation to engage the blank tobe shaped and bring it in contact with the live center, the rods 107 engage each a blank on one side of the one between the centers, so the blanks on both sides are engaged. The blank in front of the one to be shaped is pressed against the yielding rest 114: and

'the one in" the rear of the one in operative position is pressed against the rigid rest 116 and both blanks are held firmly during the shaping of the blank between, whereby their displacement is prevented. When the shapingoperation is finished and the back center with its clamping rods 107 is withdrawn, the blanks on each side of the one just shaped are released andthe blank which is in front of the one in operative position and the one justshaped are moved longitudinally along their seats by the spring 11 1 which has been slightly deflected by the clamping pressure and now recovers its normal position; in this way, the center is cleared. p

Toremove the necessity for indenting the ends of the blanks to receive the shiftable or back center84, the latter is provided with a serrated or cupped surface 120 to engage the blanks and the center, and is mounted to rotate in its stock 110 and provided with anti-friction bearings. The stock 110 is bored centrally at 121 and the back center is provided with a collar 122 of such diameter that it will rotate freely within the bore 121 when it is supported concentrically therewith. Beyond the collar, the diameter of the centering pin 101 is reduced, forming a cylindrical shank 128, and the stock 110 is counter-bored to receive the shank, and the diameters of the bores and shank are such that the latter is permitted to revolve freely. A groove 124 encircles the shank 123. Balls 125 are placed between the collar 122 and the base of the bore 121. A pin 126 inserted rigidly in and through the stock 110 engages in the groove 124 to prevent dis-- placement of the center 84. Thus, we have the thrust of the back center taken up by anti-friction bearings. It is permitted to rotate freely and the only resistance offered to the rotation of the blank by the live center is the slight resistance to rotation of the bearings of this pin.

The pneumaticgathering means by which the dust and shavings are removed from the neighborhood of the shaping cutter is an important feature of my invention. A hood 117. incloses the shaping cutter (see Fig. 3), and is open toward the carrier. An outlet is provided at 118 and to this a suitable pump or exhauster is connected. A second hood 119 is placed below the seats, the mouth of the hood being close to the inner surface of the carrier and extending from the entering position to and beyond the shaping position. Suitable connections are provided blank in the seat, and is withdrawn.

serves as a means for holding the blanks in their seats. I

It will be understood that each blank, after being shaped, is released by the live and dead centers 83 and 84, and finally by the second clamp 107; it remains in its seat and advancesv to the slotting cutter. The carrier stops as each seat comes in line with the slotting cutter, the seat being so placed that as the cutter swings forward, it enters the slot therein. In this position, it is necessary to hold each blank at one end. This is accomplished by means of a sliding jaw 127 which is caused to descend on each blank as it arrives opposite the slotting cutter and to hold it firmly in its seat during slotting. The jaw 127 is mounted to slide vertically in bearings 128 on the frame of the machine. The jaw is actuated by means of a bell crank lever 1.29, one arm 130 of which is horizontal in its middle position. The extremity of this arm engages the slot 131 in the jaw 127. The other arm 132 is pivotally connected at its extremity to the connecting rod 133 which is pivoted at its other extremity to the lever 92. The operation of this device is so apparent that it hardly needs descrip tion. As each seat on the carrier comes in line with the slotting cutter, the roller 98 encounters the high portion of the cam 99 whereby the upper extremity of the lever 92 is moved to the left, (see Fig. 2) the bell crank lever 129 rotates left-handed about its center, the arm 130 moves downward and the jaw 127 is depressed, engaging the blank. The cutter now swings forward, slots the The cam 99 is so timed as to release the blank when it has been slotted. The carrier moves forward and the blank which has just been slotted, still in. its seat, approaches the receptacle 135. A chute 136 which terminates just beneath the carrier leads to this receptacle, (seeFigs. 1 and 3).

The pins are ejected from their seats by means of two stationary cams 138 and 139,

. (see Figs. 1 and '3). These are both placed in the path of the seats and an appreciable I distance aft of the slotting position, the cam 138 being in advance of the cam 139. The former overlies the cylindrical surface of the carrier, extending transversely of the seats and placed close to the carrier surface. This cam is curved in a cylindrical plane from the path of the ends of the seats toward the path of their central portions, so that each pm, as it advances and comes 1n contact with the cam surface, is moved along in its seat so that it extends beyond the carrier on the side opposite to the cam 138. On this side of the carrier, in the path of the portions then caused to project, is the cam 139 which is curved in a plane at right angles to the axis of the carrier from a point just beneath each seat to a point a considerable greater radial distance from the axis of the carrier than are the seats. Each pin, as it is acted upon by the cam 138, is moved over so that its extremity comes in line with the cam 139, and as the carrier moves forward, the pins so displaced are engaged by the cam 139 and lifted from their seats. At this point, they fall onto the conductor 136 and slide into the receptacle 135.

The operation of the machine has been so far described in connection with its construction that further description thereof is thought tobe unnecessary. Though specific details of construction have been carefully set forth in order that persons skilled in the art may build an operative machine of the form which is at present preferred these details may be varied to a wide extent within the scope of our invention.
